Well elecs checked out at mech, he reckons guage fried when link stuffed up. Said get a non stepper motor tacho- they don't work well off coils. He checked temp guage agrees its sensor.


Guage manufacturer recommends running an rpm filter when using with coil as it won't get clean stable signal, making warning light stay illuminated. Wôrked ok before fusibke link though ??

He wasn't concerned by tapping again. So Looks like new tach or work out where and what rpm filter is?
